Computing Genus 1 Jacobi Forms
Martin Raum
We develop an algorithm to compute Fourier expansions of vector valued modular for Weil representations. As an application, we compute explicit linear equivalences of special divis…
M24-twisted Product Expansions are Siegel Modular Forms
Martin Raum
Cheng constructed product expansions from twists of elliptic genera of symmetric powers of K3 surfaces that are related to M_24 moonshine. We study which of them are Siegel modular…
Harmonic Maass-Jacobi forms with singularities and a theta-like decomposition
Kathrin Bringmann, Martin Raum, Olav Richter
Real-analytic Jacobi forms play key roles in different areas of mathematics and physics, but a satisfactory theory of such Jacobi forms has been lacking. In this paper, we fill thi…
Explicit computations of Siegel modular forms of degree two
Martin Raum, Nathan C. Ryan, Nils-Peter Skoruppa +1
Unlike classical modular forms, there is currently no general way to implement the computation of Siegel modular forms of arbitrary weight, level and character, even in degree two.…
